Descripción del Dataset

Clasificador de especies de pingüinos basado en atributos físicos usando Decision Tree

Dataset de pingüinos del archipiélago Palmer (Antártida) con medidas físicas para clasificación de 3 especies: Adelie, Chinstrap y Gentoo.

Información General

Autor: gusdelact
Fecha de creación: 2026-05-18
Fuente original: gusdelact/penguins
Licencia: Apache-2.0

Composición del Dataset

Filas: 344
Columnas originales: 7
Variable target: species (Adelie, Chinstrap, Gentoo)
Features numéricas: bill_length_mm, bill_depth_mm, flipper_length_mm, body_mass_g
Features categóricas: island, sex

Preprocesamiento Aplicado

Renombrado de columnas a formato snake_case
Simplificación de nombres de especies (nombre completo → nombre corto)
Eliminación de columnas no relevantes para clasificación (studyName, Region, etc.)
Clipping de outliers con IQR (factor 1.6)
Imputación de valores faltantes (mediana para numéricos, moda para categóricos)
Escalado StandardScaler para variables numéricas
One-Hot Encoding para variables categóricas
Separación train/test estratificada con ratio 0.25

Distribución de Clases

Adelie: ~44%
Gentoo: ~36%
Chinstrap: ~20%

Uso Previsto

Dataset curado para entrenamiento de modelos de clasificación de especies de pingüinos.

Limitaciones

Dataset pequeño (344 observaciones)
Solo 3 islas del archipiélago Palmer
Datos recolectados entre 2007-2009
